I hope this gets fixed, although I don't believe it. I care about the noise emissions. AFAIK they are measured on a real road, but only up to 50 km/h and in a ridiculous narrow test. Harley Davidson and other are known to optimise for this test with movable parts in the exhaust pipes so these get much louder when the bikes goes faster than 50 Km/h.

Well, as much as a cheat it is, I'm happy that those bikes can go quiet on slow (city) streets but as loud as possible on the highway (increase security and swag).

I'm always surprised when people don't realize that large bikes are suppose to be loud so that drivers can hear them coming. It's a necessary evil.

I'm a motorcyclist and I'm downvoting this fallacy. If this were seriously the case then good beginner bikes like the Ninja 250 and Honda CBR250R would be unsafe, especially for new riders. Enjoy your loud pipes if you like (I do on my throaty Aprilia) but don't pretend they give you any safety benefit to balance the annoyance it causes some people.

Who should write the software then? People who don't know anything about cars?

People who know software, sitting in the same room as people who know cars. I fear a big company would find it impossible, but that's how you get good software.

Are you under the impression they don't hire programmers to write their software? I don't understand your point.

If your vehicle can't be safe without annoying everyone within a quarter mile radius, it's too unsafe to be on the road.

Anyone know if this "defeat device" would be a violation of the various Euro* regulations in Europe? It's been widely reported [1] that diesel cars emit more NOx than the specification allows, but so far no consequences. More than 50% of all cars sold in the EU are diesel fueled, and many countries are breaching the EU air quality limits. This causes an estimated 400,000 premature deaths each year [2] [1] http://www.…

Apparently made illegal at least by 2007 regualtions (maybe adopted later, not expert in EU law)

This is actively malicious. There had better be criminal charges filed.

Criminal charges seem like a good plan. But its not sufficient. Volswagen has over a period of time pumped a lot of this gas into the atmosphere and the fine ought to reflect the actual clean up damage. What is it going to cost to remove it and put the environment back to the way it should have been if they hadn't broken the law. That is what these sorts of fines ought to be based on.

No fines should be punitive so they dont do it again. It is not about clean up with particulates, it is about their medical effects, which you cant be specific about.

The NYT is being disingenuous in presenting this as VW detecting the EPA test cycle and doing something to cheat. I think they've confused open loop and closed loop engine operation. VW's 4-cylinder engines which failed the EPA tests are all turbo engines. Turbo engines run hotter than naturally aspirated engines and so, they produce more NOx, since it's one of the high temperature byproducts. In fact, EGR (exhaust g…

> The NYT is being disingenuous in presenting this as VW detecting the EPA test cycle and doing something to cheat. I think they've confused open loop and closed loop engine operation. The NYT is not at all confused. The cars in question have software in the ECM specifically meant to detect testing. The software looks at various inputs, including steering wheel position, speed, duration of operation, and barometric p…

Wow, jumped the gun on giving VW the benefit of the doubt before reading the actual complaint. Thanks for the link.

When I last bought a VW (2008) I was concerned due to a clunking noise after first starting it up and driving a few miles; I called the VW service dept and they explained that there was a compressor which captured exhaust fumes and released them at a lower rate for the first few miles of each journey -- to help them meet EPA emissions standards. I was assured there was nothing to worry about. While this is a differen…

Some models of the Yamaha R1 have an intentional flat spot in their fuel maps which happens to be right at the spot where testing happens, too. In a similar vein, the Aprilia RSV4 kind of cheats at noise testing: in neutral, there is a baffle which flips down to dampen the exhaust note a bit. :)

Almost all supersport bikes coming into the US utilize both of these strategies. :)

I own a Ducati 999 that was lemonlawed because it would stall at stop lights. Super common and happened because of how lean the bikes had to run to pass US emissions.

More interestingly: Did the German TÜV not detect this? They have even stricter rules.

And completely different emission and OBD requirements. I don't know how much hardware they share, but they definitely use different software.

Yes, but the TÜV should have noticed such faking, too.
